M. S. Tillack,
with a lot of help from C. Kessel
ARIES Project Meeting
22 – 23 Sept. 2013

2. Changes were made to ASC since September
Adjustments to calculation of xl
Removed factor of 0.8 on Pdiv
Corrected and updated (line average vs. separatrix) density formula
New radial builds (Oct 27 version)
Edge radiation fractions (input) revised
Edge radiation to FW set to zero (was 10%)
Core radiation to divertor set to zero (was 10%)
Economics fixes (per Waganer presentation in Sept 2012)
Updated price deflator base year (to 2009) and data ( )
Updated unit cost data
Unfortunately, bugs still remain in the COE algorithms

3. Implementation stayed the same
Overnight runs on PPPL cluster, 21 parallel jobs
Post-filtering:
Start with 412,690 physics solutions
58,080 of these are viable (finite COE)
80 survive filtering, as follows:
990 ≤ Pnet < 1010 MW
R ≤ 7 m
bN ≤ 0.05 (for a total b of 6)
fGW ≤ 1
H98 ≤ 1.7
fBS ≤ 0.925
Keep only points having COE within 5% of the minimum. 43 remain. Worst of 80 survivors is 11% higher.
